Navigate to to configure the global DNS settings for your LANCOM R&S®Unified Firewall.
Important:
The DNS server settings are usually specified by the WAN connection. You should only need to configure the DNS server settings if you cannot obtain them over the WAN connection.
In the General Settings editing window you can modify the following parameters:
| Input box | Description |
|---|---|
| Acquired Servers | Listed here are the DNS servers that have been learned via DHCP and PPP connections or similar. |
| DNS Servers | This table allows the configuration of 1 to 2 DNS servers per zone. A zone is a specific DNS area like "*.company.intern". The default zone "*" is the zone that every DNS address falls into that doesn't fall into a specifically defined zone. The setting "AUTO" is valid for the default zone only. It cannot be used in combination with manually specified IP addresses; it must stand alone. If set to "AUTO", the automatically learned DNS servers listed above are used. In addition, it is possible to specify via which connection the entered servers can be reached. For the DNS server entry with "AUTO" as the assigned server, the Acquired Servers are used. If a connection was assigned to this entry, e.g. dsl, then all referred servers are displayed, but only the servers that were referred via the connection "dsl" are used. If no connection is selected for the "AUTO" entry, then all sourced servers are used. You can sort the table according to your needs, with the exception of the default zone which is always the last element and cannot be deleted. |
| Multicast-DNS-Relay | Activate the multicast DNS relay here. Multicast DNS (mDNS) is an alternative to conventional DNS for resolving host names in (small) networks. Here, rather than requesting the name resolution from a server, a request is sent to and processed by all of the hosts that can be reached through the multicast address. Popular implementations of mDNS are Bonjour (Apple) and Avahi (Linux), which enable various devices (e.g. network printers) to be networked without having to perform any configurations beforehand. |
